2. Extension.extension
Definition	May be used to represent additional information that is not part of the basic definition of the element.

Definition	An Extension May be used to represent additional information that is not part of the basic definition of the element. To make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension.

Comments	There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone.

Definition	Specifies a value that each occurrence of the element in the instance SHALL follow - that is, any value in the pattern must be found in the instance, if the element has a value. Other additional values may be found too. This is effectively constraint by example. When pattern[x] is used to constrain a primitive, it means that the value provided in the pattern[x] must match the instance value exactly. When an element within a pattern[x] is used to constrain an array, it means that each element provided in the pattern[x] must (recursively) match at least one element from the instance array. When pattern[x] is used to constrain a complex object, it means that each property in the pattern must be present in the complex object, and its value must recursively match -- i.e., If primitive: it must match exactly the pattern value If a complex object: it must match (recursively) the pattern value If an array: it must match (recursively) the pattern value If a pattern[x] is declared on a repeating element, the pattern applies to all repetitions. If the desire is for a pattern to apply to only one element or a subset of elements, slicing must be used. See Examples of Patterns for examples of pattern usage and the effect it will have.

592. Extension.extension:pattern[x].value[x]
Definition	Specifies a value that each occurrence of the element in the instance SHALL follow - that is, any value in the pattern must be found in the instance, if the element has a value. Other additional values may be found too. This is effectively constraint by example. When pattern[x] is used to constrain a primitive, it means that the value provided in the pattern[x] must match the instance value exactly. When an element within a pattern[x] is used to constrain an array, it means that each element provided in the pattern[x] must (recursively) match at least one element from the instance array. When pattern[x] is used to constrain a complex object, it means that each property in the pattern must be present in the complex object, and its value must recursively match -- i.e., If primitive: it must match exactly the pattern value If a complex object: it must match (recursively) the pattern value If an array: it must match (recursively) the pattern value If a pattern[x] is declared on a repeating element, the pattern applies to all repetitions. If the desire is for a pattern to apply to only one element or a subset of elements, slicing must be used. See Examples of Patterns for examples of pattern usage and the effect it will have. Value of extension - must be one of a constrained set of the data types (see Extensibility for a list).

Slice Name	pattern[x]
Definition	Specifies a value that each occurrence of the element in the instance SHALL follow - that is, any value in the pattern must be found in the instance, if the element has a value. Other additional values may be found too. This is effectively constraint by example. When pattern[x] is used to constrain a primitive, it means that the value provided in the pattern[x] must match the instance value exactly. When an element within a pattern[x] is used to constrain an array, it means that each element provided in the pattern[x] must (recursively) match at least one element from the instance array. When pattern[x] is used to constrain a complex object, it means that each property in the pattern must be present in the complex object, and its value must recursively match -- i.e., If primitive: it must match exactly the pattern value If a complex object: it must match (recursively) the pattern value If an array: it must match (recursively) the pattern value If a pattern[x] is declared on a repeating element, the pattern applies to all repetitions. If the desire is for a pattern to apply to only one element or a subset of elements, slicing must be used. See Examples of Patterns for examples of pattern usage and the effect it will have.

388. Extension.extension:pattern[x].value[x]
Definition	Specifies a value that each occurrence of the element in the instance SHALL follow - that is, any value in the pattern must be found in the instance, if the element has a value. Other additional values may be found too. This is effectively constraint by example. When pattern[x] is used to constrain a primitive, it means that the value provided in the pattern[x] must match the instance value exactly. When an element within a pattern[x] is used to constrain an array, it means that each element provided in the pattern[x] must (recursively) match at least one element from the instance array. When pattern[x] is used to constrain a complex object, it means that each property in the pattern must be present in the complex object, and its value must recursively match -- i.e., If primitive: it must match exactly the pattern value If a complex object: it must match (recursively) the pattern value If an array: it must match (recursively) the pattern value If a pattern[x] is declared on a repeating element, the pattern applies to all repetitions. If the desire is for a pattern to apply to only one element or a subset of elements, slicing must be used. See Examples of Patterns for examples of pattern usage and the effect it will have.

Definition	Specifies a value that each occurrence of the element in the instance SHALL follow - that is, any value in the pattern must be found in the instance, if the element has a value. Other additional values may be found too. This is effectively constraint by example. When pattern[x] is used to constrain a primitive, it means that the value provided in the pattern[x] must match the instance value exactly. When an element within a pattern[x] is used to constrain an array, it means that each element provided in the pattern[x] must (recursively) match at least one element from the instance array. When pattern[x] is used to constrain a complex object, it means that each property in the pattern must be present in the complex object, and its value must recursively match -- i.e., If primitive: it must match exactly the pattern value If a complex object: it must match (recursively) the pattern value If an array: it must match (recursively) the pattern value If a pattern[x] is declared on a repeating element, the pattern applies to all repetitions. If the desire is for a pattern to apply to only one element or a subset of elements, slicing must be used. See Examples of Patterns for examples of pattern usage and the effect it will have.

974. Extension.extension:pattern[x].value[x]
Definition	Specifies a value that each occurrence of the element in the instance SHALL follow - that is, any value in the pattern must be found in the instance, if the element has a value. Other additional values may be found too. This is effectively constraint by example. When pattern[x] is used to constrain a primitive, it means that the value provided in the pattern[x] must match the instance value exactly. When an element within a pattern[x] is used to constrain an array, it means that each element provided in the pattern[x] must (recursively) match at least one element from the instance array. When pattern[x] is used to constrain a complex object, it means that each property in the pattern must be present in the complex object, and its value must recursively match -- i.e., If primitive: it must match exactly the pattern value If a complex object: it must match (recursively) the pattern value If an array: it must match (recursively) the pattern value If a pattern[x] is declared on a repeating element, the pattern applies to all repetitions. If the desire is for a pattern to apply to only one element or a subset of elements, slicing must be used. See Examples of Patterns for examples of pattern usage and the effect it will have.
